Why the Japanese Government can afford to rebuild: it qwns the largest deposit bank in the world. The Japanese government can afford its enormous debt because it owns the bank that is its principal creditor. But competitors are attempting to force the bank’s privatization. If they succeed, they could propel the country into debt servitude along with other credit-strapped nations.

When an IMF spokeswoman said at a news conference on March 17 that Japan has the financial means to recover from its devastating tsunami, skeptical bloggers wondered what she meant. Was it a polite way of saying, “You’re on your own?”

Spokeswoman Caroline Atkinson said, “The most important policy priority is to address the humanitarian needs, the infrastructure needs and reconstruction and addressing the nuclear situation.

As U.S. Vice President Dick Cheney said, “Deficits don’t matter.” They don’t matter, at least, when you own the bank that is your principal creditor. Japan has remained impervious to the speculative attacks that have crippled countries such as Greece and Iceland because it has not fallen into the trap of dependency on foreign financing.
